Guided Notes
Key concepts students will learn:
- •
A compound inequality has more than restriction on the set of x's that satisfy the equation.
- •
When solving compound inequalities with 'and', the solution must satisfy both inequalities, while with 'or', the solution must satisfy at least one inequality.
- •
Interval notation uses brackets to include the endpoint and parentheses to exclude the endpoint in the solution set.
